Sealing application of blind flanges
There are three types of blind flange sealing surface: plane type sealing surface, suitable for occasions where the pressure is not high and the medium is non-toxic. The concave and convex sealing surface is suitable for occasions with slightly higher pressure; the mortise and sealing face is suitable for inflammable, explosive, toxic medium and high pressure occasions. Ordinary rubber gaskets are suitable for occasions with temperatures below 120 degrees. Asbestos rubber gaskets are suitable for occasions where steam temperature is below 450 C, oil temperature is below 350 C, and pressure is less than 5MPa. For general corrosive media, acid resistant asbestos boards are most commonly used. A gasket is a circular ring that produces plastic deformation and has a certain strength.
